This adaptor converts the standard 3.5mm smartphone headset plug to an Shortel and Polycom RJ9, RJ10, or RJ22 handset plug, allowing you to use your favorite smartphone headset with your newer VoIP office phones. The adapter outputs binaural sound for stereo headsets, meaning you will hear sound out of both ears. The adapter cable is approximately five inches long.
**Works best when paired with an amplifier**
